O’Neill Development’s Passive House/Zero Energy Initiative

The Chelsea House in Bethesda.

O’Neill Development recognizes the sound principles of sustainability and the importance of “Green Building” and is committed to best practices in this area. Back in 2010 O’Neill Development, along with green architect David Peabody, were the first to design and build a “Passive House” in the Washington Metropolitan area and the 22nd in the United States… The “passive” method of construction originated in Germany and involves creating a super insulated structure with constantly re-circulating fresh air and even temperatures throughout. A PH home uses roughly 90% less heating and cooling energy than the average home. It is designed as an integrated system, with site, energy, ventilation, air quality, humidity, health and comfort all taken into account.

Since that first Passive House in Bethesda, MD, O’Neill and Peabody have built their second and third passive houses in Rockville, MD and Prince Georges County, MD areas respectively. The latter is a modular passive house completed for the Housing Initiatives Partnership for sale to a low/moderate income buyer. This PH is the first modular passive house in the Metro region. O’Neill and Peabody are currently building under contract a net zero house built with Passive House principles but not certified as PH in Arlington VA.
